It is interesting if the protocols of communication between radio module PCB and main board of TX are same in old TX and this new one. Maybe someone can check?
What for - for having 1 TX with two modules inside.)

That's about the max this heli can take. If you keep the 328A in a good right hand banking turn, it can fight it off. Other than that, you're dead in the wind. But it's certainly respectful considering it's weight.

I have been flying at 8 minutes consistently now across the 3 batteries I have. My longest flight so far was 9:18 when the battery decided to quit. It looks like if you start picking a landing spot at 8 minutes, you should have great battery life.

There are a couple things I'm not crazy about so far. The first is the canopy. I haven't cracked it yet, but it sure seems like I'm going to. It's the same material as the 260A, but since it's bigger, it feels flimsier.
The battery design is pretty good, but the "pull flap" to remove it from the holder is at the top, and has gotten caught in between the main gear and pinion which you can imagine doesn't have the greatest of results.
Servo extent (in stock transmitter settings) could be better also. I would like to see just a bit more forward and back throw, but I can understand why they limited where it's at. I haven't had a boom or canopy strike since I've had the heli. I'm going to start messing with the TX settings to see what adjustments can be made.

Now the good things. Durability is excellent. Today I flew it into a tree at full throttle and only lost a tail blade (which I found, and wasn't broken). There is definitely a cutoff in the RX to prevent stripping the gears and ruining the motor. I've cut throttle at 10-15 feet and still haven't broken the skids. I haven't even popped a linkage yet, which was the first thing I thought would ground me. So I'm extremely happy with that aspect so far.
Stability is pretty obvious with this flybar configuration. But it self stabilizes very smoothly, instead of the abrupt nose up tendancy. It will still nose up, but it stabilizes more like a boat coming down from plane. Much smoother than I'm used to seeing.
The tail motor is pretty solid, but is very noisy. You can even hear it in the short video that was just uploaded. It seems to sound like its working much harder than it actually is. I've got close to 30 flights now, and it's holding up great.
Main motor power is not stunning, but certainly adequate. You have plenty of pull out power and head speed is good. After 8 minutes of flight, it's warm, but not burn your finger hot.

All in all, it's everything I was hoping it would be. It's certainly a solid backyard bird that enjoys being tossed around. Great job, NE!

Sounds promising. I haven't seriously considered getting a bigger than SP size heli, since most of the times I'm limited to indoor flying, but this does sound tempting. It seems like a very smooth heli, that at the same time likes to be tossed around. Flight times of 8 minutes also sounds nice.

See the unused holes in the main shaft, just above the flybar? Looks like an easy mod to alter the head to a 90 degree setup, perhaps not enough clearance from the main rotors though. Still, I wonder why they are there?
